Responsibility (n.) for deaths after a war lies not with the regime that inherits the wreck but with those who wrecked it.
Responsibility (n.) attaches to the predictable consequences of your own actions, not of someone else's — which is why a citizen should aim criticism first at his own state.
Responsibility (n.) weighs most where one can act: a citizen's own state's crimes matter morally far more than an enemy's, because he can help stop them.
Responsibility (n.) made ambiguous is responsibility abolished: the enemy's killings have one clear author, the ally's simply happen.
Responsibility (n.) grows where you can do the most good, which is usually where you share in what is being done.
